Using data from the Ocular Hypertension Treatment Study and other studies, Dr. Steven Mansberger discusses what is known about the role of cataract surgery in lowering IOP in glaucoma patients. In this presentation from the 2012 Annual Meeting, Dr. Mansberger also discusses in which patients cataract surgery alone is indicated, how to decide between cataract alone or combined cataract and glaucoma surgery, and its role in end-stage or high-risk glaucoma.
